If the duct system was correctly sized for the old furnace, and the new furnace is the same or greater heating capacity, you likely need some changes to your duct system.
Modern furnaces move more air for the same heating capacity than older furnaces, as much as 50% more airflow for the same heating output.

feel your pain

just wonder if your furnace is still loud. I just had a york affinity 8.s installed. now my house is like a factory. Installer came in 8 times, couldn't fix it. York technician claimed everything works fine. If that is the case, they need to re-evaluate the product design. Or they should warn their customer about this. So annoyed.

I have that discussion with salesmen quite frequently. They always tell me that they don't have time. I say BS. You can let the folks look at your equipment brochures while you drill a couple of holes and measure ESP. It takes less than 15 minutes to evaluate the duct system.

You're selling comfort systems...not boxes!

Hard to get salesmen to check the static.We have found that if they don't, they get to share the cost to make the duct changes,works real well.

Unless both of them were idiots (which I highly doubt), they both knew that your problem was the duct work and air flow.
